This has been a long time coming for a number of reasons... But I can FINALLY taste it!! New house was finished just over a year ago and the basement dedicated theater room construction is wrapped up. Sealed boxes for the 6 Volt-10's were built prior to the triple green glued drywall and installed in the ceiling for Atmos. Just finished building the 8 HTM-10 flatpacks that will handle surround duty (front wides, front/back side surrounds, and rear surrounds). Xovers are all finished for the Volts, HTM's and Titans (the DIYSG PCB’s are incredible, by the way).
Rack with the XLR's and speaker wiring is finally routed, labeled and complete. Rack consists of Emotiva RMC-1, Emotiva XPA-DR3 (LCR duty), two Emotiva XPA-7's (one for the left side and one for the right side of the non-LCR speakers) and a SpeakerPower SP2-12000-DP (with room and wiring for a 2nd amp in the near future). The side surrounds are currently run on the same signal with y-cables until Emotiva gets their ***** together to bring us the speaker expansion modules, processing to support higher speaker count layouts (i.e. 11.4.6) and Dirac...
The adjacent AV closet houses two racks, one for the theater equipment and the other for home automation/whole house audio/etc. The theater rack has a dedicated 100-amp subpanel with plenty of power on tap - all amps will be run on 240v. I built power cables for them with 10g wire for for the SpeakerPower amp and 12g for the others. Regarding speaker wiring, I have 10g for the LCR, 4 runs of 10g for future subs behind the screenwall, two runs of 10g to the two sub positions at the rear of the theater (for the dual SHS-24's) and 12g to all other speaker locations.
Seating was ordered from Nick at TheaterSeatStore. Went with the Pillow HR. There are two rows of seating with the back row on a riser. Front row is 3 individual seats and back row is 4 connected seats with the outer two seats curved. Expecting these to arrive within the next few weeks. As soon as the seats are on their way, I’m going to order the JVC NX7 projector and a Seymour Center Stage XD Premier 145” 2.35 screen.
On to the Titan and SHS-24 details: I've been reading forum posts and modeling these in my head for over a year now and finally got around to finalizing my plans. The dual woofer Titans were inspired by the build thread that
put together and obviously a HUGE thanks to
for making the kits possible and answering my many questions!
at Databass brought me back into reality on the SHS-24 build and I decided sealed would be a better option for me (I had originally planned to go with huge ultra low tuned enclosures). 12 cubic feet on 6000 watts will allow me to use most of the SHS-24’s enormous xmax and give me gobs of bass flat into the single digits. I plan on additional subs up front in the near future, so losing some SPL going sealed vs ported isn’t the end of the world for the first build (famous last words of an AVS DIY member).
DIYSG Dual Woofer Titan “630LX” Enclosures (x3 for LCR):
- Overall Dimensions: 71”H x 20”W x 23.6”D
- 6cf per woofer tuned to ~30Hz
- Port (per woofer): 2.25”H x 18.5”W x 13.43”L
- 1” MDF baffle and ¾” MDF everywhere else
- 10” “dead” space in the base to clear the bottom of my drywalled screenwall
SI SHS-24 Sealed Enclosures (x2):
- Overall Dimensions: 37.75”H x 37.75”W x 21”D
- 12cf internal volume
- 1” MDF double baffle and exterior panels with ¼” rabbets
- ¾” MDF bracing
Here are models of the enclosures from Fusion 360. I'm happy to share the CAD files if anyone wants to build these or check them out closer. My cabinet guy is going to be cutting these panels on the CNC soon and I’ll update this thread with progress. Let me know if you have any questions!
